Abstract (en)
A wind tunnel for testing aerodynamic surfaces, comprising a rotor (50) defining a cylindrical cavity for circulating a gas around the periphery of the cavity, first and second elements each having inner (83,89) and outer (87,91) surfaces extending between a nozzle end (101) and an exhaust end (103) of the wind tunnel, the elements being mounted in opposed relation in the cavity, the inner surfaces of the elements cooperating to define a nozzle (90), a test region (74) and an exhaust region (114), the scoop surface disposed proximate the nozzle for diverting a predetermined portion of circulating gas through the nozzle, test region, and exhaust region, the exhaust region being open to the cavity to permit the diverted gas to rejoin the circulating gas, and a sting for mounting the aerodynamic surface in the test region.
